What's new

v5.3 [10 Nov 2017]
- Overhauled, Yosemite-style UI. We’ve made iDefrag fit in with the latest version of Mac OS X.
- Simpler, easier to understand statistics. The old statistics tab was dense and hard to understand. We’ve simplified and refined the information, and put it in the sidebar.
- New “Selected Files” algorithm. You can now select multiple files and tell iDefrag to defragment them all at once.
- Better handling of bad blocks. We’ve improved the way iDefrag deals with bad blocks; it will now tell you which file is affected and carry on with the rest of the disk.
- New documentation. We’ve rewritten the documentation to make it easier to read.
- Improved support for Retina displays. iDefrag will look even better on that new 5K iMac…

v2.1 [22 Sep 2011]
Defragment individual files
Select and defragment individual files without touching the rest of your disk.
No bootable CD/DVD required!
iDefrag no longer needs a bootable CD/DVD; instead, simply click Go and iDefrag reboots your machine into a special mode allowing you to defragment without using a separate boot disk.
Improved performance
iDefrag 2 is the fastest version yet, including numerous performance tweaks to speed up defragmentation.
Improved user interface
For version 2, we’ve overhauled the user interface to reduce clutter and improved accessibility for disabled users.
